Correlation between clinical and laboratory parameters and early pregnancy loss in assisted reproductive technology cycles: A cross-sectional study
The miscarriage rate after pregnancy resulting from assisted reproductive technology (ART) is about 20%, roughly half of which is biochemical. The correlations between the number and quality of oocytes, estradiol level and early pregnancy loss have not been fully clarified.
This study aimed to examine the clinical and laboratory parameter effects on early abortion in ART cycles.
In this cross-sectional study, 408 women who were ART candidates and were referred to the Yazd Infertility and Research Center, Yazd, Iran during March 2017 to March 2020 participated. Women who had a fresh embryo transferred and who had a positive beta human chorionic gonadotropin serum test were included in the study. The Anti-Müllerian hormone (AMH) level, embryo quality, oocyte number, progesterone level, estradiol level, and maternal age were extracted from the medical records.
No significant difference was observed in the age, mean estradiol and progesterone levels on trigger day, number of MII oocytes, and embryo quality between the groups (p = 0.19, 0.42, 0.07, 0.34 and 0.20, respectively). No statistically significant difference was found between the 3 groups of AMH level (p = 0.20). After evaluation using logistic regression, the rate of negative clinical pregnancies was higher in the group with AMH < 1 ng/ml. However, this was not found to be statistically significant.
We did not find any correlation between early abortion and AMH levels, embryo quality, oocyte number, progesterone level, estradiol level, or maternal age.
